Rachel early $34 in 4 hours at her job today she wants to know how much she can earn tomorrow if she works 10 hours at the same
Natalka [10]

Answer:

$85

Step-by-step explanation:

Hi! First you need to divide $34 by 4 to see how much money she makes each hour.

$34 / 4 = $8.50

Now that you know how much she makes an hour, you can multiply this by 10 to find how much she will make if she works 10 hrs.

$8.50 * 10 = $85

Rachel will make $85 if she works 10 hrs.

Hope this helps!

Find the value of m for which mx^2 - 6x + 5 = 0 has one solution.
insens350 [35]

Answer:

m = \frac{9}{5}

Step-by-step explanation:

Given a quadratic equation in standard form ax² + bx + c = 0 ( a ≠ 0)

Then the discriminant Δ = b² - 4ac gives information on the nature of the solutions.

For the equation to have 1 solution we require b² - 4ac = 0

mx² - 6x + 5 = 0 ← is in standard form

with a = m, b = - 6, c = 5, then

b² - 4ac = 0

(- 6)² - (4 × m × 5) = 0

36 - 20m = 0 ( subtract 36 from both sides )

- 20m = - 36 ( divide both sides by - 20 )

m = \frac{-36}{-20} = \frac{9}{5}

Daniel wants to prove that the interior angles of any triangle sum to 180°. He draws a line through one vertex parallel to the o
Serggg [28]

Alternate interior angles theorem.

<u>Step-by-step explanation:</u>

By using the definition of Alternate Interior Angles theorem, we can say that If a transversal cuts any two parallel lines, then those pairs of alternate interior angles are seems to be  congruent.

So in the given triangle,

∠4 ≅ ∠2

∠5 ≅ ∠3

Sum of all the angles in a triangle = 180°

∠1 + ∠2 + ∠3 = 180°

Since from the above congruence, we can write that

∠1 + ∠4 + ∠5 = 180°

Hence proved.
